The Euler totient theorem generalizes a theorem by this man, while another statement by this man can be proved using the Taniyama conjecture regarding elliptic curves. Snell's law can be derived from his principle that the path taken by a ray of light is the one which can be traveled in the least amount of time, while a statement he proposed was only recently proven by Andrew Wiles in the 1990's. For 10 points, name this French mathematician who stated that there are no integers n greater than 2 which satisfies the equation a to the n plus b to the n equals c to the n, known as his last theorem.
